Quan en Jack va morir no va se acceptat al cel per ser una persona molt mísera i no voler compartir els seus diners.It seems that Jack also had played tricks on the Devil, who wouldn't let him into hell, either. Jack was stuck. He had to walk the earth, holding a lantern, until Judgment Day.

This is the story that has been told by the Irish people who went to America in the 1800s. They carved their turnips into the face of "Jack-of-the-lantern" to remind themselves what happened to people who were misers. And in the fall, pumpkins are much easier to find than turnips.So that's why Americans today carve their pumpkins into jack-o-lanterns
